[WINNING esas sonyconvetrinev STRUCTURES.

ISg United States,

and useful Improvements'in Runni for Conveying lowing is a descriptio to the accompanying Structures,

part of this specification.

relates to conveying struc- Tlie invention tures.

This application cons my copending to the running gear o ture.

The object of a running gear propelling structure alo rails by means o WATsoN,

and resident in the' county yof Milwaukee 5 and State of lVisconsin, have invented new ng Gears of which the foln, reference being had drawings, which are a titutes a division of application for conveying structures, Serial No. L113,017, filed v ber 27, 1920, and relates more particularly Septemf the conveying structhis .invention is to provide for positively drivingthe f a propelling ng the supporting gear' and'pin rack, the pin rack being associated in a novel manner with the supporting rail.

further consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

The invention In the drawings:

of a conveying s ning gear embodying is an end elevation of Fig. 1; Fig. 3 is the propelling away and parts is a section conveying Fig. 1 is a side tru the structure elevation' cture provided withlrunthe invention; Fig. 2

shown in a detail side view of one of trucks, parts being broken being in section, and Fig. 4

taken on the line 1r-4 of Fig. ;k Referring to the drawings, the illustrated structure comprises a c on'veying bridge 5, the'trucks 6 of which are mounted on wheels 7 is mounted on the ing 10 drives a bevel gears 12 mes 13 on transmission A `brake 16, either of the mechanical d for stopping the or dynamic type, is use rotation of the shaft 11.r

The running tion includes the whe rails 8 and driving a prope Y 6, including rack hereinafter The propelling shaft 18 journa running on rails 8. A motor 9 bridge and through gearline shaft 11 which carries hing with similar gears shafts 14 carrying gears gear embodying the invendescribed.

lled in bearings 1 els 7 and supporting mechanism for the trucks llingwheel 17 yand a pin wheel' 17 is mounted-on a 9 on ythe clear of any foreign matter. 'may be of one piece or they may have a ptmler 27,k '19207 Serial No.- eiaoiv; Divided ananas appiicaurm sied January saisies.4 i l f f.

posed in upright position between the head and base ofthe rail 8 and are secured there- .to at intervals by clamps 25 which also engage the base of the rail and serve as rail clamps. rFliese clamps 25`have a top surface 26 upon which the plates 23 rest. With this construction, as the plates 'are not rigidly connected with the rail, the rail may expand and contract independently of the rack, and dirt and dust are excluded froml the space 27between the rail 8 and the plate 22. The plate 23 vis elevated above the roadbed by the rail `clamp 25, thus providing open spaces 28 between said plate andthe roadbed so that the pins 24 may be easily kept clean and The pins 24 roller portion engaged by the wheel 17. The weight of the conveying structure is taken by the rails 8 so relieved of any strain yoccasioned by this weight. In practice the rack is anchored at each end of the yards in any suitable manner. f

I desire it to be understood that thisinvention is not tofbe limited to any specific formor arrangement of parts except in so far as such limitations arek specified in the claims. y`

`What I claim as my invention is: 1. Running gear for conveying structures comprising a truck, a rail, supporting and guide wheels for said truck and running on said rail, a plate labutting one side of the i,

the rail to` rail, anchoring means securing the roadbed and the plate to the rail, anotherl plate supported on'ysaid anchoring means above the roadbed-and pins joining said plates together and coacting therewith to form a pin rack, and a propelling wheel on the truck engageable with ksaid rack.

2. Running gear for conveying structures that the driving pins are y spaced from n ythe first namedv plate, transversely disposed comprising a truck, a rail, supporting' and guide wheels for said truck and running on said rail, a plate secured against one side of the rail, another plate supported above the roadbed and spaced from plate, transversely disposed pinsjoining said plates togetherl and coaeting therewith to form a pin rack, and a propelling Wheel on the truck engageahle With said rack.`

3. Running gear rfor conveying structures comprising a truck.I a rail, supporting and guide Wheels for said truck and running` on said rail, a plate disposed against one side of the rail, anchoring means `securing the rail to thc roadbed, another plate supported on said anchoring means and spaced from the lirst named plate` transversely disposed pins joiningsaid plates together and coactthe lirst named` ing therewith to form a pin rack7 and a propelling Wheel on the truck engageable With said rack.

4. Running gear for conveying Structures eoinprisinga truck, a rail, supporting and guide' Wheels carried bythe truck and'running on said rail, aplate disposed against one side of the rail,` anchoring means secur ing the rail to the roadbed and the plate to the rail, another plate spaced from the roadbed and `from said first nained plate, transversely disposed pinsjoining said plates together and @cant-ing therewith to form a pin rack7 and a propelling Wheel on the truck engageable with said racln i In testimony whereof I aHiX my signature.
